I want to make sure everyone knows that I just released my software called "Yobit pump alert". THis is custom software that uses an algo to detect the start of a pump here on yobit, the second it starts. YOu can even filter the coins you see by price. Most pumps start less than 100 sats , so you can easily filter the cheap coins, so they are the only ones displayed https://bitcointalk.org/index.php?topic=1945937.msg20241953#msg20241953

Is the LM75 the actual temp sensor itself as well? if it is then measuring the temperature on that location of the board is purely a freaking ambient temp - "inside of the cube" temp ROFL! Thats quite useless, thanks KNC.

As far as I'm concerned, kfc put the LM75 as far as possible away from the chip to try to hide how stupidly hot their chips were getting. This was my thoughts the moment they released photos of the neptune boards.

BTW, anyone else notice how they put the component that reports the chip temperature at the very *edge* of the board, far far away from the chip? Is this a tell that KNC expect Neptune to have heat/overheating problems?

If you have a few big fans blasting air over this, it is not going to report anywhere near the correct chip/board temperature. It looks like KNC are misrepresenting - by design

So, then the Temperature column on status page is strictly a ambient reading only =)

Well, I would really advise you to investigate markings on all chips on the board and see if any other contains something LM75-compatible. It should be fairly easy and safe to do the tests by touching the plastic cap of the chip with a soldering iron and look for any temperature readout to rise sharply.

The continuing popularity of an obsolete chip like LM75 was perplexing to me. Apparently it is still being used as in the last-resort over-temperature protection circuits. When not programmed in any way it will power-up as an over-temp protection set to trigger at 80 degrees Celsius.

On this miner it may be wired up to shut it down when the in-cube ambient temperature goes over 80C, which will serve as a sort of pre-fire-protection circuit even if the programmable controllers are hung or disconnected.

The firmware source code clearly shows its polling the LM75 IC for temperatures to populate the Temperature fields on STATUS page on webgui.

You can order a precompiled firmware with no donations. Look in my signature for the order page. Thanks for testing the security system

the chips were getting so hot that it discolored the machined edge on the copper pipes used to make contact with the chips

Ya, many of the failures are from the wafers getting so hot, the solders balls scorch and lose contact with the pcb. I may have to look into a reball machine. Problem is there is no stencil made to my knowledge for this chip.
